My DD was 7.5 lb. I had the epi with her,due to very high blood pressure. It was an uncomplicated birth, 6 hours all up i think.
My DS was 9lb 4 oz. I went 7 days over my due date. I was told that he would just be an average sized baby at pretty much every Dr's app i had. He came out pretty easy aswell (well as easy as child birth can be lol) I didn't have any drugs.

I'm also only about 5'2, so don't be to to freaked out about having a big baby
